I the threadguide pulley, and Fig. 7 represents a detail central sectionof'the same.

The machine whichis generally represented 1n'F1g, 1,:forms the subjectmatter of my PatentNo. 990,564, April 25,1911, and consequently it'xwillnot be particularly I described herein. j This machine includes,however, in addition totheparts to be more speclfically describedhereafter, ith-read deliv ery mechanisms'l', thread windingmec'haelongated hollowbodynportion 4, and a cap i 5 therefor. 3

1A polishingband 6 is=removably secured attwoplaces on'xthe body portionof the heater by the. screws 7, 8. This band 6 Fig. 3 ;v and a coilspring9 is-mountedin the upper end of the body portion of the heater,

for yieldinglv holding the band 6 snugly in position on theheatertpasses, over the cap 5, as'is well shown in Theheater is shown in thepresent instance as being fitted to be heated by steam, and, to thatend, there is provided 'a main steam'inlet pipe 10'and a main steamexhaust pipe 11, the inlet pipe 10 being mounted within the exhaust pipe11. Theexhaust pipe 11 has a branch pipe 12 which is screwed into thelower end of the bodyxportion 4"ofthe heater, as indicated at 13 whilethe inl'etpipe 10 has abranch 14 which 21' passes up through the branch12 into the in-- terior of the bodv portion 4: of-the heater, andextends nearly to the top thereof.

The body portion 40f the heater is coveredon all exceptfone sidethereof, vizf the r J? side on which the band 6 is mounted, with anonheat-conducting acket 15 composed of materialsuch as asbestos fiber,and the pipes 11 and 12 are also covered in the same manner. V Thepurpose 'andeffect lot this no'nt1;

heat-conducting jacket is to prevent the outside pipes 11,12, and theparts of the heater with which the thread being polished does not comein contact', from losingv a consider;

able amount of heat through radiation; and thus a given degree oftemperature may be maintained in the unjacketed side of the heater, viz:the 0116.011 whichtheband .6 is. heat ng mea mounted,with a less amountof; dium than has heretofore been required, owing to the fact thatconsiderable heat losses have been experienced through the radiationfrom the steam pipes and. unus dportions of the heater.

.Tlheheater i soformcdthat one endottlie surface'on which the band 6 ismounted is wider than the other end-"of: thersaid. surface; in thepresent instance, the upper end of; this: surfacei's shown as: the widerone. The purpose of. widening out thlSzSlllffiCG at the top is in orderto provide-suflicientroom for thethread which is: beingrpolished' to be1 rolled: back: and forth on theband- 6 which conforms to theshapeof-this surface. In asmuch. as this rolling of. the thread isperformed: by: thereciprocating rods 3 which are. located at.v one endonly of the heaters,-

' it isr not necessary to makethe endof the heating surface whichis.farthest from the rodsi3. aswi'de as theu-pperend of thegsurefaceslwhich are'near the rod It isdesirable, therefore, tomakethe lowerend of the heating surface as narrow asis feasible'in' order tomake theheater lighter, avoid the use of unnecessary materialin the heater, andin particular obviate: any; wastejof ma terial in the-bandl 6 for thereason that this band. is commonly composed of aluminum which isquiteexpensive.

A threadrguide pulley-is mountednear one end oli the heater, inthe-present instance: at they lower end of the heater, to which it" issecured-by a cap screw 16 This thread guide pulley comprises.flYCfl-Slfl'lf" 17 which has a pairof thread retainers 18:soarrangedthat thread may bepassed between them when it isdesi-red to do sowhilepreventing the thread from falling out of line with the pulleywheel in; case the thread: maybe slackened for any cause. Vithin this:casing is a pintle 1 9 on. which is rotatably andremovablymounted apulley wheelwQO: One end of the casing 17 is-open forthe'removal ofthe'wheel' 20' when-it is! desired to, clean or replace the same, and acover 21 is pivotallysecu-red to thecasing 1,? by the screw 22;

which cover is: designed to normally'close the open end of the casing 17The thread in the course of being: polished passes from the threaddelivery'mechanism L downrin contact with the-band 6" on the heater,around: the pulley 20 and up again in contact with the bandit? totthethread winding. mechanism 2:

By: the for-In and: construction of the heater and thread guiderpulleyhereinave described, there; is promotedva'n economy of .1heatingfmedium, hence anecenomirof fuel about halfas much aluminumas hasheretofore been necessary in making a polishing band for a, heater ofa-given sizehaying means for holding the-band snugly thereon.The-arrangementofi the heaters in the machine sothat the thread passesup and down the front side of the heatenfpermits the heaters tobe-placed closer together than; has

heretofore: beeny'customary, inasmuch as;

there "is little necessity ":of-=reaching in bee; tween 'the=-heaters;the placingnof; ithe thread:

a The j'acketingof theapipes; and heatnr withnon-heatconducting-material? not: only promotes the economy'of heatingmedium hereinabove. mentioned, but alsorabsolutel'y prevents theoperator: from, burning his or her arm whenlt 1s necessary-to;in'sertthearm in: between the-heaters, for instance, for thepurpose of-unscrewingthe screwTtqre; move the polishing band,
